Textile finishing for intelligent thermoregulation
Adaptive cooling fabrics that respond to body heat for lasting comfort
HeiQ Smart Temp™ is a patented thermoregulation technology designed for textiles. It enables fabrics to dynamically respond to changes in body heat and moisture, supporting the body’s natural temperature regulation instead of working against it.
When the wearer becomes warm and moisture builds up, the technology increases evaporative cooling. As the body cools down and moisture levels decrease, the cooling effect gradually decreases. This adaptive behavior helps maintain a more balanced and comfortable wearing experience over time.
At the core of HeiQ Smart Temp™ are hydro‑functional polymers developed by HeiQ. These polymers reversibly change their behavior with temperature and moisture, allowing the fabric to react when needed and remain neutral when not.

The science behind HeiQ Smart Temp™

As long as the body is hot, it supplies heat and sweat which is used by the fabric to achieve prolonged cooling. When the body heats lowers, the level of sweat is reduced and the cooling effect of the fabric adapts. This behavior allows the textile to respond dynamically rather than delivering a constant effect. The result is a more balanced thermal experience that follows the wearer’s activity level and body conditions.

Don’t see the answer you’re looking for?Explore HeiQHeiQ offers the following thermoregulation test methods for your textiles:
- Dynamic Evaporation Test*: Measures how efficiently a textile supports evaporative cooling under changing conditions.
- FLIR (Forward Looking Infrared) thermal test**: Uses infrared imaging to visualize surface temperature changes and heat distribution.
- Sweating manikin test**: Simulates heat and moisture release from the human body to assess thermal and moisture management performance.
- Sweating torso test**: Focuses on the upper body to evaluate localized thermoregulation and moisture evaporation behavior.

HeiQ Smart Temp™ focuses on adaptive thermoregulation that responds dynamically to body heat and moisture. HeiQ Cool™ is designed to deliver an immediate cool-to-the-touch effect plus continuous evaporative cooling. In simple terms, HeiQ Cool™ emphasizes instant and lasting cool sensation, while HeiQ Smart Temp™ emphasizes adaptive cooling for ultimate comfort.
HeiQ Smart Temp™ and HeiQ Synbio Dry™ both improve moisture comfort in textiles, but serve different purposes. HeiQ Smart Temp™ is an intelligent thermoregulation technology that reacts to body heat, dynamically increasing evaporation to cool the wearer and maintain optimal temperature. HeiQ Synbio Dry™ is a bio-based moisture management technology powered by probiotics that accelerates water spreading and evaporation, enabling faster drying and a consistently dry feel.
Yes. Different textile finishes can be combined on the same fabric to deliver multiple effects at once. The key is formulation and process control. Finishes must be compatible and engineered to work side‑by‑side during application and remain stable during use and washing. Well‑designed combinations extend fabric functionality without changing how the textile feels or behaves in daily wear. For example, a garment can manage moisture while also reducing odour build‑up.
